VACUUM-CLEANER.

Specification of Letters Patent.

Patented Sept. 1.1914.

To all whom it may concern:

Be :it known that 1,-W1LLIAM S. SUTTON, a citizen of the United States, residing at Rockford, in the county ofWinnebago and State of Illinois, have invented certain new and useful Improvements in Vacuum-Cleaners, of which the following is a specification..

- parts.

The object of this invention is to construct a vacuum cleaner, in which the dust collector, exhaust fan and muffler are closely arranged, and in the details of construction of the various parts.

In the accompanying drawings, Figure 1- is 'a vertical section through the operative Fig. 2 is a side elevation of the lower portion of the cleaner. Fig. is a horizontal section through the dust collec-. tor and ,muffier on dotted line a a Fig. 2.v Fi 4 is a section on dotted line b b Fig.2.;

nection with the screw 9 connected to the base. A motor 10 is supported by the shelf 5', and a belt 11 connects the motor with the suction fan. The dust collector comprises the drum 12 having a hopper-shaped lower end 13. A removable-receptacle 14 is held against the lower end 13 of the drum 12, and a packing ring 15 is located between lower end of the drum.

The means for holding the receptacle in connection with the drum 12 is essentially a toggle joint mechanism and comprises a bail 16'having its ends 17 pivoted to the eceptacle. To the bail near each end there of is pivoted a link 18 having. its free end iii hook form. The hooked ends of these links engage studs 19 extending from the lower portion 13 of the, drum 12. When the upper end of the receptacle and the;

the receptacle 14 is held in connection with the drum, the bail will appear as shown at F g. 2. By raising the hail the receptacle Wlll drop from immediate connection with the drum, permitting the link to be removed from the studs 19, and as the bail is pivot-.1- ally connected to the receptacle, the recep tacle may be carried by the bail. Ahead 20' 1s secured to the upper end ofthe drum 12, and has a central screW-threaded opening within which is secured a pipe 21. Fromthe underfacfe of the head 20 depends a. flange 22 to which is secured one end of a fabric tube 23, the other end of this tube is secured to a metallic tube 23% connected to the collar 24. and held in connection with. the pipe 21 by the lock'nut 25. The pipe 3 communicating withrtheg'exhaust fan has- 1p; other end onne lfifid' with the head 20, anftleomniunicates' with the space between thefabric tube 23- and'the tube 233}.

The drum 12 is supported by a bracket 26 extending from the base 1. A vacuum gage 27 is located in a pipe 28 having one' end communicating with the pipe 21, and .its other end .connected with the head 20' and communicatingwith the interior ofjthe drum 12 but inside the space included between the fabric tube 23 and the metallic tube 23?}. Cocks 29 and 291 are located in the pipe 28, one each side of the gage 27. A check valve 30 is located in the pipe 3 and is of the vertical type and closes in its. upward movement. From a T 31 in the pipe 3 extends a pipe 32, to the free end of which is connected a relief valve 33 having its lower branch formed with a valve seat 34 uponwhich is seated a valve 35, from which is suspended a weight support 36 upon which maybe placed weights 37. The

base 1 is'ifo'rmed with an air passageway 38 leading' 'from the lower portion of the exhaust fans, I

A muflier" is supported by .a connection with the base 1, .and comprisesfan outer cas-' ing 39 provided with a side opening {1Q communicating with the passage-way38i A' pipe 41 extends through the side'openingQ in the outer casingof the mu'fiier and has its end extending downwardly This pipe 41is provided with a valve 12 for closing 7 its upper portion. A pipe 43 connects with V cated a vertically movable plunger 51 which the pipe 41 also with the pipe 3 and a valve 44 is placed. in this plpe. A receptacle 45 is held against the lower end of the outer casing of the mufiler by a bail 46 of the same-construction as the bail 16 employed to hold the dust receptacle in position.-. I A pipe 47 has ascrew-thread vconnection with the upper end of the outer casing of the muflier. Within the outer casing 39 is'lo-- cateda tube 48 having both ends open, and 1.-

arranged in series in the lengthwise direction of'the tube, Within the tube 48 is lois tubular and has its upper end closed.

I The lower'end 52 of this inward. To the upper c of the tube 48.

- in by the fan will be forced out through thepassage-way 38 into the outer casing 39 of the muflier and into the fplunger 51 thereby raising it until some 0 47 As the air pressure varies so wil plunger 51 move vertically and uncover more or less number of the openings. If the air pressure from the fan 2 was constant, the plunger would be unnecessary, as the proper:

number of openings could be provided. I

In order to secure quletxunning acertain" clearance between the working parts of the fan is required. In order to fill this s ace om pipe 41 by virtue of its connection with. vacuum pipe 3 will cause the liquid to rise and flow through pipe 41, valve 44, pipe. 43 and into fan through vacuum' pipe 3, and after passing through fan, the liquid passes while running, .the exhaustion'of air through outlet into passage 38 and opening 40 into receiver 45 securing continuous circulation.. The check valve 30 located in vacuum pipe 3 is normally.- open so that no resistance is offered to the passage of air, when the flow of air is discontinued the vacuum in the large drum 12 will close the valve 30'and prevent the liquid-from relunger' is turned lbsed end of the plunger 'issecured an inverted cone 53. This? plun er is capablejof a vertical movement within the tube'48, and its upward move;- ment is limited by coming in contact with j the stops 54 projecting inward from the top'of the outer casing of the mufiier, and.' its lower movement will be limited by the f fiange 55'thereof rest g on the upper end ceptacle 45 being drawn over into the drum 12.- Should oil or water be carried by the airinto the plunger 51 it will strike against the cone' 53 and innerface of the plunger and run down-and drop into the receptacle.

The airncarrying dust drawn from the sur,-: faces,being cleaned-will enter the dust collector by way of he pipe 21 and pass into the' 'con'ical air tig t tube 23% WhlCl]. on account of its increased area in the direction cause the dust to separate and fall into the receptacle" '14 provlded -:for the purpose which can be removed when full. As greater or less suction is required to do difierent grades of cleaning, I have provided the relief valve with weights 37 which can' be applied as required to vary the suction of the flow of air will tend to expand it. and- I through the dust collector, as the valve 35 will open when the suction has reached the ipredetermined ressure corresponding with jweightsap lie This enables very delicate fabrics to e cleaned likewise the heaviest car ets or draperies. f1...- .1 norder to ascert the condition of the fabric tube, that is, the quantity of dust adihering to it and which. might in time interfere with the'passage' "of air through 1t, the

v v cocks 29 and 29% are provided. If cook 29 is In use the suction fan is rapidly revolved which will create suction in the pipe 3, and in its connection with the dust collector, suc- .open with cook 29 closed and-the gage ,Iregisters' a certain gure, then'if cock 29% is opened and the pressure falls'to a lower 'figufre, the extent of the drop w'illfindicate quantity of dust adhering to it. 'When it is :necessary-to place water 1n the water recepithe condition of the fabrictube, that is, the i Qtacle, it can'be accomplished by opening the v valve 42, which communicates with a source the openings 50: areexposed through which the 'air will es cape into the space between the tube 48 and outer casing and escape by way of thelpipel of. supply.
